On Feb first week I was diagnosed of uti my GP gave me a course of antibiotic. I took the full course in between I got chicken pox and I took antiviral for that but it's a few days now in the morning I am experiencing burning sensation while urinating which stays for a while and I have a bit frequency and urge to go, during the night time I need to urinate like every 3 hourly is it uti again???
